Spring coroutines AOP is not compatible with `@Cacheable`

[malaquf]

Affects: 6.1.8

---

When combined with other aspects on a suspend function like in the following example, the interceptor does not handle the aspect chain properly and aspects like TimedAspect are not executed.

@Timed("MyService.doSomething")
@Cacheable("something")
suspend fun getSomething() {
	...
}

The TimedAspect is executed if the annotated function is not a suspend function.

I tried to run it with @EnableCaching(mode = AdviceMode.ASPECTJ) for testing it but I get the following error during startup:

Caused by: java.lang.IllegalStateException: Expecting to find 3 arguments to bind by name in advice, but actually found 2 arguments.

There have been several follow-up fixes in this area. Could you try this against the just-released 6.1.11 please?

The regular interception might still not work for coroutines, but at least the AdviceMode.ASPECTJ problem should go away.

Hi @jhoeller, thanks for the fast response. I've just tried it with 6.1.11. Unfortunately, the behavior is still the same.
